MIC5219

500mA-Peak Output LDO Regulator

General Description

Features

The MIC5219 is an efficient linear voltage regulator with high

peak output current capability, very low dropout voltage, and

better than 1% output voltage accuracy. Dropout is typically

10mV at light loads and less than 500mV at full load.

• Guaranteed 500mA-peak output over the full operating

temperature range

• Low 500mV maximum dropout voltage at full load

• Extremely tight load and line regulation

• Tiny SOT-23-5 and MM8™ power MSOP-8 package

• Ultra-low-noise output

• Low temperature coefficient

• Current and thermal limiting

• Reversed-battery protection

• CMOS/TTL-compatible enable/shutdown control

• Near-zero shutdown current

TheMIC5219isdesignedtoprovideapeakoutputcurrentfor

startup conditions where higher inrush current is demanded.

It features a 500mA peak output rating. Continuous output

current is limited only by package and layout.

The MIC5219 can be enabled or shut down by a CMOS or

TTL compatible signal. When disabled, power consumption

drops nearly to zero. Dropout ground current is minimized to

helpprolongbatterylife.Otherkeyfeaturesincludereversed-

battery protection, current limiting, overtemperature shut-

down, and low noise performance with an ultra-low-noise

option.

Applications

• Laptop, notebook, and palmtop computers

• Cellular telephones and battery-powered equipment

• Consumer and personal electronics

The MIC5219 is available in adjustable or fixed output volt-

ages in space-saving SOT-23-5 and MM8™ 8-lead power

MSOP packages. For higher power requirements see the

MIC5209 or MIC5237.

• PC Card V and V regulation and switching

• SMPS post-regulator/dc-to-dc modules

• High-efficiency linear power supplies
